ABSTRACT:
A vacuum urological surgical irrigating solution-collecting system of the continuous flow type employs a flexible thin-walled disposable collecting receptacle in a rigid outer supporting container, with spacers to hold the collecting receptacle away from the outer container and to establish a space therebetween. A higher vacuum is maintained between the collecting receptacle and the rigid container walls than is inside the collecting receptacle. A fine-adjustment vacuum regulator is employed to maintain the required balanced urological relative pressure conditions between the inside and the outside of the vacuum collecting receptacle to maintain said receptacle in a fully expanded condition. The spacers consist of perforated half-cylindrical rigid strips arranged vertically with their side edges secured to the inside surface of the rigid container wall and with their rounded faces directed inwardly. A circular bottom spacer is provided between the bottom of the collecting receptacle and the bottom of the outer container, and a top spacer disc assembly is provided between the top of the collecting receptacle and the rigid container top cover.
